Using Nuclei v3.2.0 works flawlessly for the same target url and command line arguments.

@s1d6point7bugcrowd it should be fixed with linked Pr in that issue #4895 (comment)

[s1d6point7bugcrowd]

Got it. Thanks

I'm facing the same on latest version. The issue occured to me while using a list of private templates but it does not happen when using public nuclei templates.
